Without a working thermometer it is inpossible to say. Heat bulbs come in wattages ranging from 25 watts to 150+. Plus everyones homes have different airflow patterns that will effect the cage.
Personally I would do the following to heat the cage:
Under tank heater to provide the basking temperature of 90 degrees. Under tank heaters MUST be regulated by a thermostat. Without one they can get hot enough to kill a BP in a matter of hours. Also keep in mind that under tank heaters do not change the temperature of the air in the cage.
I would then use 2 low wattage infrared heat bulbs (these produce a light that doesn't disturbed them so they can be left on 24/7) controlled by lamp dimmers to keep the air temperature/cool side at 80 degrees 50-75 watt bulbs like these will work: http://m.petsmart.com/mt/www.petsmar...uctId=11147193
As for thermometers/hygrometers I would get one of these
They are avaliable at most Walmarts for $12. They measure 2 temperatures and humidity. The probe will be on the hot side sitting directly over the under tank heater, and the box will sit in the cool side. The box will measure the cool side temps and humidity.

I personally wouldn't recommend tubs for a room that is 65 during the summer... They would be a nightmare to keep the cool side warm enough.
